HORSESHOE.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed July 11, 1914. Serial No. 850,303.

To all whom it may concern Be it known that I, MICHAEL CHARLES NOLAN,gentleman, a subject of His Majesty the King of Great Britain andIreland, residing at The Cliife, Alcester road, Bromsgrove,l/Vorcestershire, England, have invented certain new and usefulImprovements in Horseshoes, of which the following is a specification.

This invention has reference to horse shoes and is directed to improvethe grip on slippery surfaces and prevent slipping particularly ontarmac roads.

My improved horse shoe is formed from a cross grooved and ribbed steelor other Inetallic bar, the crossribs being so shaped as hereinafterdescribed as to form a plurality of teeth on the undersurface of theshoe extending across the shoe from side to side and continuous fromheel to heel one side of each of the said teeth being substantially atright angles to the surface of the shoe and the other side of each ofthe said teeth being inclined and concaved from the surface to the baseof the substantially right angled side of the adjoining tooth.

The short length of rolled steel or other metallic bar for forming oneof my improved horse shoes has on one face of it the alternate crossgrooves and cross ribs which are formed in the act of rolling the bar bythe rolls which are correspondingly cross grooved or ribbed, or thealternate cross grooves and ribs are formed on the bar by other meanssuch as by milling. The said bar is heated and bent into the shape ofthe shoe and it follows that the teeth on the finished shoe will be ofsubstantially the same shape and size all round the shoe from heel toheel and the right angled or nearly right angled sides will on one sideof the shoe be toward the heel and on the other side of the shoe will betoward the toe thus being equally eifective in preventing the horsesfoot from slipping forward or backward or sidewise.

My invention is illustrated by the accompanying drawings of which Figure1 illustrates my improved horse shoe; Fig. 2 is a cross sectionalelevation of the same taken on line X X of Fig. 1; Fig. 3 is aperspective view of a piece of ribbed bar for forming the said horseshoe.

The cross grooves a and ribs 72 extend right across the underside of theshoe from side to side and each of the ribs 6 between the cross groovesis of the form above stated, that is to say, each rib has one side 1made at right angles or nearly at right angles to the face of the shoeand the other side 2 is inclined to the face of the bar and is madeslightly concave and extends to the bottom of the right angled or nearlyright angled side 1 of the next rib b and the tips 3 of the teeth areflattened forming two sharp edges 4, 5 where they join the sides 1, 2.

It is to be understood that the teeth are of the same shape and size allround the shoe from one heel to the other and it will be seen that theyafford a good foot hold and effectually prevent the horses foot slippingeither backward or forward or sidewise and this will continue until theteeth are nearly worn away as owing to their shape as aforesaid, theedges 4, 5 of the teeth remain sharp as they wear.

It is to be understood that my improved shoes are made from a shortlength of rolled or milled bar of which a portion is shown in Fig. 3,having the said alternate ribs 6 and grooves a extending all along thesame from end to end.

What I claim as my invention and desire to secure by Letters Patent is Ahorse shoe formed from a cross grooved and ribbed steel or othermetallic bar the cross ribs forming a plurality of teeth on theunder-surface of the shoe extending across the shoe from side to sideand continuous from heel to heel one side of each of the said teethbeing substantially at right angles to the surface of the shoe and theother side of each of the said teeth being inclined and concaved fromthe surface to the base of the substantially right angled side of theadjoining tooth, the right angled side of the teeth of one side of theshoe facing toward the heel and the right angled side of the teeth ofthe other side of the shoe facin toward the too.

In testimony whereof I aflix my signature in presence of two witnesses.

MICHAEL CHARLES NOLAN.
